MF morini clutch

My Negrini has a Franco Morini 4mp/s turbo motor, it is running fine but it has a bit of clutch drag. cable adjustment is fine so i thought i would try and adjust it inside the cover, thinking it would be a simple lock nut and screw adjuster, (which it may well be )  like a bantam and many others. So far I haven`t got the little cover of the side due to a poor head on a screw, before I go any further, does anyone know if there will be an adjuster like that underneath ?  See exploded diagram attached, i think part 67 is maybe it ? but when i try to blow up the picture it loses definition,   I don`t have the notes to go with the drawing, which would probably answer my question...
